Qi's idea is just to get a Linux kernel and run it.  Hopefully it won't
need extending itself beyond that so it's maintainable and reliable.

If a boot menu is wanted, just point Qi at a kernel + initrd or mini
rootfs that provides the boot menu action, it can then allow as
beautiful a boot menu as you like using normal Linux libs and tools, and
either chroot into the final rootfs or kexec into a second kernel from
the final rootfs.  I guess it should all fit in 3MB or so.

Such a kernel + rootfs can be pretty chopped down and then fast, since
typically there's a lot of stuff you don't need for that job (eg, whole
networking stack unless you want features around that).
